【 摘 要 】

In this paper, an approximate closed-form solution for trajectories of ballistic projectiles is derived. The assumption made in this derivation is to neglect the variation of the elevation angle along the trajectory in a small interval of time. The closed-form solution has been used to develop the 3-logarithm for a lead angle computation as well as faster computation of trajectories. The fact that one of the analytical expressions although complex, is invertible and is made use of in the algorithm.
